20+ practice questions focused on Network Services — one of the most tested topics on the CompTIA A+ Core 1 220-1201 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Network Services PracticeA technician is troubleshooting a network where users can access the internet but cannot reach a specific internal web server by its hostname. The server's IP is 10.0.0.5, and pinging 10.0.0.5 works. The technician checks the DNS server and finds an A record for the server's name pointing to 10.0.0.10. What is the most likely issue?
Explanation: The DNS A record points to the wrong IP address (10.0.0.10 instead of 10.0.0.5), causing hostname resolution to fail for that server. This is a common DNS misconfiguration where the record does not match the actual server IP. Correcting the A record resolves the issue.
A company deploys a load balancer to distribute traffic across three web servers. Users report that they occasionally see outdated content or are asked to log in repeatedly. Which network service configuration is most likely missing to maintain session persistence?
Explanation: Load balancers distribute traffic but without session persistence (sticky sessions), a user may be directed to different servers during a session, losing login state or cached data. Configuring the load balancer to use cookies or source IP affinity ensures the same server handles the session. DNS round-robin alone would cause similar issues.
A user configures their laptop to use a static IP address, subnet mask, and default gateway. They can ping other devices on the same subnet but cannot reach the internet. What network service is most likely missing from their configuration?
Explanation: With a static IP, the user must also configure a DNS server address to resolve domain names. Without DNS, they can communicate locally but cannot access internet resources by name. DHCP would auto-assign these settings, but static configuration requires manual entry.
A company wants to allow employees to securely access the corporate network from home using their laptops. Which network service should be deployed to provide encrypted remote access?
Explanation: A VPN (Virtual Private Network) creates an encrypted tunnel between a remote device and the corporate network, ensuring secure data transmission over the internet. DHCP and DNS do not provide encryption, and port forwarding alone does not secure remote access.
A user reports that they can access internal resources using IP addresses but cannot access them using hostnames. Other users on the same network have no issues. What is the most likely cause?
Explanation: The ability to use IP addresses but not hostnames points to a DNS resolution problem on the user's device. This could be due to a misconfigured DNS server address in the network settings or a local hosts file issue. Other users working normally suggests the problem is client-specific.
